The release of methane and carbon dioxide from the melting of eternally frozen Arctic waters will add $ 70 trillion ($ 98 trillion) to the global bill on climate change, a new study says.
This feedback loop, in addition to the loss of heat diverting white ice, will cause global warming and its cost to rise by five percent.
The study, published in Nature Communications, is the first to calculate the economic impact of the melting of eternal ice.
With current 3 ° C warming trajectories by the end of the century, it is expected that the melting of the ever-frozen waters will result in the release of 280 gigatonnes of carbon dioxide and three gigatons of methane, which is 20 times more powerful than the climate.
According to the authors, the Arctic backwater chain will increase global warming by five percent if countries do not improve their emission reduction commitments under the Paris Climate Agreement.
Researchers say the figure of $ 98 trillion is 10 times higher than any expected benefit of Arctic melting, such as access to minerals or better shipping routes.
Permanent freezing is any land surface that remains completely frozen at 0 ° C for at least two years, usually located in high latitudes around the Arctic and Antarctic regions.
This is published in a study published yesterday in the National Academy of Sciences reports that Greenland's ice sheet melts six times faster than four decades ago.
